It's important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you'll need the right hitch. Here aresome rules to follow: Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sureto seal the holes later when you remove the hitch. If you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "Carbon Monoxide'' in the Index). Dirt and water can, too. The bumpers on your vehicle are not intended for hitches. Do not attach rental hitches or otherbumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safetychains to dragon the ground. Trailer Brakes Because you have anti-lock brakes, don't try to tapinto your vehicle's hydraulic brake system. If you do, both brake systems won't work well, or at all. Be sure to read and follow the instructions for the trailer brakes so you'll be able to install, adjust and maintain them properly. 4-44
